2- 12 C160G01A-GAT To Keep Locks from FreezingTo keep the locks from freezing, squirt an ap- proved de-icer fluid or glycerine into the keyopening. If a lock is covered with ice, squirt it withan approved de-icing fluid to remove the ice. Ifthe lock is frozen internally, you may be able tothaw it out by using a heated key. Handle theheated key with care to avoid injury. NOTE: The proper temperature for using the immo-bilizer key is from -40°C to 80°C. If you heatthe immobilizer key over 80°C to open thefrozen lock, it may cause damage to thetransponder in its head. C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approved anti-freeze solu-tion in accordance with instructions on the con-tainer. Window washer anti-freeze is availablefrom Hyundai dealers and most auto parts out-lets. Do not use engine coolant or other types ofanti-freeze as these may damage the finish.
C160B01A-GAT Snowy or Icy ConditionsTo drive your vehicle in deep snow, it may be necessary to use snow tires or to install tirechains on your tires. If snow tires are needed, itis necessary to select tires equivalent in size andtype to the original equipment tires. Failure to doso may adversely affect the safety and handlingof your car. Speeding, rapid acceleration, sud-den brake applications, and sharp turns arepotentially very hazardous practices. Duringdeceleration, use engine braking to the fullestextent. Sudden brake applications on snowy oricy roads may cause skids to occur. You need tokeep sufficient distance between the vehicle infront and your vehicle. Also, apply the brakegently. It should be noted that installing tire chainson the tire will provide a greater driving force, butwill not prevent side skids. NOTE: Tire chains are not legal in all provinces.Check province laws before fitting tire chains. C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethyl- ene glycol coolant in the cooling system. It is theonly type of coolant that should be used becauseit helps prevent corrosion in the cooling system,lubricates the water pump and prevents freezing.Be sure to replace or replenish your coolant in
C160D01F-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect the battery and cablesas described in Section 6 (See page 6-18). Thelevel of charge in your battery can be checkedby your Hyundai dealer or a service station. C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight" oil be used during coldweather. See Section 9 for recommendations. Ifyou aren't sure what weight oil you should use,consult your Hyundai dealer. C160F01F-GAT Check Spark Plugs and Ignition Sys- tem Inspect your spark plugs as described in Section 6 (See page 6-8) and replace them if necessary.Also check all ignition wiring and components tobe sure they are not cracked, worn or damagedin any way.
accordance with the maintenance schedule inSection 5. Before winter, have your coolant test-ed to assure that its freezing point is sufficient forthe temperatures anticipated during the winter.

EXPLANATION OF SCHEDULED MAIN- TENANCE ITEMS
F060M01A-AAT
o Engine Oil and Filter The engine oil and filter should be changed at
the intervals specified in the maintenance sched- ule. If the car is being driven in severe condi-tions, more frequent oil and filter changes arerequired.
F060B02A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation andreplace if necessary. Drive belts should bechecked periodically for proper tension andadjusted as necessary.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replacementmore frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at theconnections. Fuel filters should be installed bytrained technicians. F060D01A-AAT
o Fuel Lines, Fuel Hoses and Connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trainedtechnician replace any damaged or leaking partsimmediately.
F060E01A-AAT
o Timing Belt Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-aged parts immediately.
F060G01A-AAT
o Vapor Hose and Fuel Filler cap The vapor hose and fuel filler cap should be
inspected at those intervals specified in themaintenance schedule. Make sure that a newvapor hose or fuel filler cap is correctly re-placed.
F060F01A-AAT
o Vacuum, Crankcase
Ventilation Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-tle rubber, cracking, tears, cuts, abrasions, andexcessive swelling indicate deterioration. Par-ticular attention should be paid to examiningthose hose surfaces nearest to high heat sourc-es, such as the exhaust manifold. Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving componentwhich might cause heat damage or mechanicalwear. Inspect all hose connections, such asclamps and couplings, to make sure they aresecure, and that no leaks are present. Hosesshould be replaced immediately if there is anyevidence of deterioration or damage.
F060H01A-AAT
o Air Cleaner Filter
A Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.
F060J01A-AAT
o Spark Plugs Make sure to install new spark plugs of the
correct heat range.
F070B01A-GAT
o Cooling System
Check the cooling system part, such as radia-
tor, coolant reservoir, hoses and connectionsfor leakage and damage. Replace any dam-aged parts. F060N02E-AAT
o Valve Clearance Inspect excessive valve noise and/or engine
vibration and adjust if necessary. A qualifiedtechnician should perform the operation.

SPARK PLUGS
YN60100A
V6
Your engine was originally equipped with plati- num-tipped spark plugs. (For 2.7L only). Platinum-tipped spark plugs will last longer than conventional type spark plugs and can be iden-tified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum-tipped spark plugs. G060B01GK-GAT
Replacing the Spark Plugs
The spark plugs should be changed at the
intervals specified in the vehicle maintenanceschedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plugs, genuine
Hyundai replacement parts are recom- mended. Recommended Spark Plugs:

Changing the Spark Plugs
You will find it easier to change spark plugs if
the engine is cold. Always change one spark plug at a time. This helps avoid getting the wiresmixed up.
1. Remove the engine rocker cover.
NOTE: It is recommended that the spark plugs for
2.7L Engines should be changed by an au- thorized Hyundai dealer.
2. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder whenthe spark plug is removed.
3. To remove the spark plug cable, pull straight up on the insulated connector, not the cable.Pulling on the cable may damage the carboncore conductor.

CHANGING THE AIR CLEANER FIL- TER
To change the filter, unsnap the clips around the cover. When this is done, the cover can belifted off, the old filter removed and the new filterput in its place. Genuine Hyundai ReplacementParts are recommended. CAUTION:
o Operating your vehicle without a proper air cleaner filter in place can result in excessive engine wear.
o Be careful that dust or dirt does not enter the air intake, or damage may result.
o When removing the air cleaner filter, be careful that dust or dirt does not enterthe air intake. These may result in dam-age to the air cleaner filter.
HGK213
WARNING: It is recommended that the engine be cool
or cold when changing the spark plugs. If the engine is hot, you could burn yourselfon the insulated connector, the spark plugor the engine itself.
4. When preparing to remove the old spark plug, guide the socket down over the spark plug, being careful not to damage the ce-ramic insulator.
5. To remove the old spark plug, turn the wrench handle in a counterclockwise direc-tion.
6. To install the new spark plug, guide the socket down over the spark plug, beingcareful not to damage the ceramic insulator. NOTE: Spark plugs should be tightened firmly. Over-
tightening can damage the threads in the aluminum cylinder head. Also, leaving them too loose can cause the spark plug to get very hot and possibly result in damage tothe engine.
7. Replace the cable by pushing the insulated connector directly down onto the electrode. Check to be sure it has snapped into placeand can't fall off.
